FAILURE HELP (Alien Autopsy)

I ran Alien Autopsy on my Alienware 13, so it isn't that old I got it in December. It said Hard Drive-ST500LM000-1EJ162 Failed SMART Short Self Test WHD16-BIG. I'm not sure what to do with this error so i need help. I'm hoping it isn't already dieing in about 2 months. So if someone could help me with this problem.
